Fog, clouds, cooling; rain possible Sunday

Orange County remains locked in a pattern of cool, moderate weather, with morning fog and afternoon clouds throughout the week, the National Weather Service says.

And though the timing is not certain, light rain is still a possibility for Sunday and Monday. Until then, the cloud and fog pattern of the past few days continues as high- and low-pressure air systems tug temperatures a few degrees up or down.

Low pressure moving inland to the north should keep air flowing from the ocean, thickening the marine layer and turning things a bit cooler through Wednesday.

Inland highs should be 68 to 73 Tuesday and 66 to 71 Wednesday; on the coast it's 58 to 63 Tuesday and about 62 Wednesday.

The pattern of low clouds and fog in the morning, partly cloudy skies in the afternoon recycles itself through Saturday, although high pressure near the coast could bump temperatures up a few degrees by Friday.

Expect inland highs of 67 to 72 Thursday, 71 to 76 Friday, and coastal highs of 60 to 65 Thursday and about 63 Friday.

On Saturday it's 68 to 73 inland, 62 at the beach.

After that, a low-pressure system approaching from the eastern Pacific could bring light rain, the Weather Service says. The chance looks slight so far for an otherwise mostly cloudy Sunday, with highs of 66 to 71 inland, 62 on the coast.

And there's a chance of rain Monday as well under partly cloudy skies. Highs should be 63 to 68 inland, 60 on the coast.
